T0 all whom it may concern.-

Be it known that we, MILES L. Davis and Jam-:s G. Rocnrxs, citizens of the United States, residing at Lancaster, in the county of Lancaster and State of Pennsylvania, have inyentcd 'certain new and useful Improvemcnts in Pretzel Cutters and Rollers, ofgitvhieh the fol-lowing is a specification, reference being hadtherein to the accompanying drawing.

Thisinventionrelates to new and useful imRrovements in pretzcl. machines.

.,n object of this invention is the provisionvo a machine of this nature in which the dough is automatically fed. in proper quantities into mechanism for rolling the Another object of this invention is the provision of a pretzel machine, in which provision is made for conveying quantities of dough from the feeding mea-ns to the rolling mechanism. l v

Stillanother object of this` invention is the employment of a' rotary table in connection with a pretzel machine, for conveying the rolled dough within the conand away from the rolling mechanism. A

A furthervobjectof this invention is the provision of a pretzelmachine inA which the operating mechanism' can he changed to adapt the machine to the making of Vienna bread. 4

A Still further object `of ,this invention is to Aimprove and simplify machines of this character, rendering them comparatively simple and inexpensive to manufacture, reliablel andeilcient in use, and readily op# .erate`d'. m Y A- .With the above and other objects in view, this invention vresides in the 'novel features of construction, formation, combination and arrangements of parts to be hereinafter more fully described, claimed, and illustrated in the accompanying dravviriizs;v in which l Figure 1, is a side elevation of our invcng tion. Fig. 2, isa top plan view thereof.

' Fig. 3, is an end elevation thereof. Fig. 4.,

is al .face view of one of the disks. Fig. 5,.

is a transverse sectional view, taken" oni the of which rises a hopper 13, for the reception of dough, A feed screw 14, is journalcd in the trough 12, and has one end disposed within a supporting cap 15; while keyed to Y the oppositel end thereof is a sprocket wheel .16. which is connected by a chain`17, to a sprocket wheel 1S, keyed to n shaft 19,' j'our nalcd in the medial hearings 20, of fthe v bracket 10. A gear wheel 21, is keyed to the shaft 19, and meshes with a drive pinion. 2i', keyed to a shaftA 23, journaled in the lower bearing 24, of one of the brackets 10. This shaft 23, is also equipped with a drive pulley 25, to which power is-applied from ay suitable source. A stationary .disk 26, is sociued to the trough 12, by anAL-Shaped bracket 27, and loosely surrounds the shaft 19; while keyed to this said shaft 19, for 'co operation with the disk26, is a corrugated rotary disk 28, which is adjustable longitudinallyof the shaft'19, to and .from the disk 26, by a screw 29, which is supported byan arm 30, which extends from the sleeve' 31. fxed as at 32, to the said shaft 19. The-disk 26, is formed .withopenings 33, and 34,- the former ofv which is"conne cted to vthe open `end 35, of the cap 15, by a curved. chute 36; While extending outwardly anddownwardly'from the opening 34,-is a discharge trough 37'.V A groove38, is formed `-in the inner face o-fjthedi'skv 26, and leads ing 40, the size of the opening 41,0f which regulates the amount of dough fedfroni the -hopper through the trough 12. A pair of bearings 42,*and 43, are secured to the-.disk

'26,' 'at its-upperand lower edges and support shafts 44, and 45, respectively. Each ofl these shafts 44, and 45, are provided f-with frictionl pulleys 46, for engagement with movement will be imparted to the shaft'44,

the edge of the disk 28, whereby. rital'y'- ze, resorted to within the scope of the appendand 45. A rotary knife 47, isw'seoured to the shaft 44, while a frictionaldisk 48, is secured to the shaft 45, to engage the edge of a table 49, mounted upon a stand 50, and lmpart a rotary movement thereto. This table 49, extends beneath the discharge trou 37. i

The disks 26, and 28, are formed with cast metal backs 51, into which Wooden bodies 52, are inserted. The faces of the wooden bodies are coated with a suitable substance and polished to prevent the dough from soaking into the wood. Y i

While in operation, the dough' is fed 'from the hopper 13 out through the bushing 40,

and a certain quantity is cut oi' by theknife 4.7, and dropped through the-chute 36, into' the groovel 38, through the opening 33.' The rotation of the disk 28, rolls and twists thedough and. deposits it into the trough 37,

from whence it is deposited upon the rotary table 19, ready for'preparation for baking. connection, that various minor changes in the specific details of construction, can be ed .c1-aims without departing from or sacricing any of the advantages of the invention.

AIt shouid he understood in this From the foregoing it will be mani-fest 30 that a pretzel machine is provided, which willfulil all of the necessary requirements of such a. device.

Having thus fully described this nvention, what we claim as new and desire to 35 secure by Letters Patent is 1. A machine of the class described,'com prising a pair of disks, one of said' disks formed with inlet and discharge openings, i andthe other disk having its inner surface 4o 2.111 a machine of the class described, the 45 combination with a stationary disk, of'a rotatable disk coating therewith, corrugations formed on saidrotatable disk, and said, stationary disk provided lwith a. formingtable disk. l
